My Virgin V+ HD box will not start up, I came home from work today and there was no connection between the box and my TV. My TV simply said 'no signal' (I am using HDMI). I have tried changing input selections which seems to make no difference. I have tried disconnecting power to the device and leaving it for some time. I have also attempted to restart the box by holding down the power button as suggested in the manual, when i did a 'STOP' message appears on the screen at the front of the box. After about 20 minutes displaying 'STOP', it changed to 'Ld:30' and has displayed the same ever since. Why wont my box work, or am i doing something wrong?
